2 Claims.

This invention relates to new and useful improvements in volatile liquidVaporizers, and more particularly to a generator for generating dry gasespecially suitable for internal combustion engine consumption on aneconomical scale.

A very important object of the invention is to provide a simplifiedmeans for vaporizing volatile liquid, with a view toward dispensing withthe present-day types of carburetor used and found on motor vehicles,aeroplanes, stationary engines and wherever volatile fuel is used toproduce combustible gases.

Another important object of the invention is to provide a specialcentrifugal means for vaporizing volatile fuels in order to produce adry, highl efficient gas.

Other objects and advantages of the invention will become apparent tothe reader of the following description.

In the drawings:

Figure 1 is a vertical sectional view through the vaporizer partlybroken away and with parts shown in side elevation.

Figure 2 is a fragmentary vertical sectional view drawn to an enlargedscale.

Figure 3 is a top plan view of the rotor assembly.

Referring to the drawings by numerals, the numeral 45 denotes a baseonto which is mounted a cylindrical shell 46. The base 45 has a well 41into which liquid fuel is fed and maintained at a certain level.

Inside of the shell 46 and above the base 45 is a rotor assembly 48comprising a plurality of finely porous rotor elements 49 ofcircumferentially grooved annular form, preferably of carbon, eachinterposed between a shoulder 50 and a nut 5| located on a verticallydisposed shaft 52. Between each shoulder 50 and its corresponding nut5|, the shaft is formed with one or more transverse ports 53, and as isshown in Figure 2, the shaft is hollow from its lower end upwardly tothe uppermost rotor element 49. Just above this, the shaft 52 ispreferably recessed to provide a socket 44 for receiving a drive shaft54. The lower end of the shaft 52 is threaded, as at 55, to accommodatea jam nut 56, while just below this, the shaft 52 is formed with adownwardly flaring formation 51 to deflect any liquid that may have atendency to creep up the shaft. Just below the formation 51 is a deepthread 58 which operates to feed any liquid that may have a tendency torise, in a downward direction.

An elongated spiral member 59 extends vertically in the shaft from thelower end thereof to the uppermost rotor element 49. This spiral memberis fixed in the shaftiz and when said shaft is rotated, this spiralserves to feed the volatile liquid from the well 41 upwardly to each ofthe rotor elements 49, and the liquid thus arriving at the rotorelements passes through these elements by capillary attraction assistedby centrifugal force in order to convert the liquid into vapor.

A hollow head section surmounts the shell 46 and is provided with abottom opening 6| to' admit gas from said shell into said section 60.Preferably a fan or impeller 62 is provided in the head section 60 fordriving by an electric motor 63 secured, as at 64, on top of the headsection 60. The fan, or impeller, 62 acts as a supercharger for the gas,or fuel, entering the head section 66. A discharge neck 65 is providedon the head section 66 for connection, in any suitable manner, to aninternal combustion engine, not shown.

As shown, the motor 63 operates the drive shaft 54 which is providedwith a recessed end 66 for receiving a key 61 on the motor shaft 68.

A horizontal partition 69 is provided in the upper portion of the shell46 with gas outlet openings Ill at the outer edge portion thereof.Upstanding bafiles H are provided on the partition sea around which thegas must pass to reach the head section 60.

A fuel inlet fitting 12 is tapped at one end into the upper portion ofthe shell 46 below the partition 69, with another end 13 thereofthreaded for attachment thereto of a fuel line 14. The remaining end 15of said fitting 12 has a valve control element 16 projecting therefromfor operating a control valve, not shown, in said fitting.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter. I

Having described the invention, what is claimed as new is:

1. A volatile liquid vaporizer comprising an upright rotary shaft, aseries of annular rotors of disc-like solid form and porous materialfitted on said shaft in superposed spaced-apart relation, said shafthaving a hollow portion extending from the lower end thereof to thelevel of the highest rotor only, pairs of diametrical ports in saidshaft in the planes of the rotors establishing communication between thehollow portion of the shaft and the inner circumferential portions ofthe rosame upwardly to the uppermost pair of ports.

2. A volatile liquid vaporizer comprising an upright rotary shaft, aseries of annular rotors of disc-like solid form and porous materialfitted on said shaft in superposed spaced-apart rela-' tion, said shafthaving a hollow portion extending communication between the hollowportion of the shaft and the inner circumferential portions of l therotors, a Well for volatile liquid into which the lower end of the shaftextends, and a helical member in' the shaft extending from the lower endof the same upwardly to the uppermost pair.

of ports, said shaft having a downwardly flared lower end portion forpreventing the liquid in V the well from creeping up the outer side ofthe from the lower end thereof to the level of the 10 shaft to saidrotors.

highest rotor only, pairs of diametrical ports in said shaft in theplanes of the rotors establishing JOSEPH F. ARMATHES.
